I guess that day the salesman come meness.. Some salesman really suck!.... But as for my case the salesman provide very good service. During the installation day he call me and check is everything ok.... After installed he call again... What surprise me is he call me the next 2day and ask me is the air- con cool enough, noise, leaking ect.... And he also help me to fill in the Warranty. Coz my PC break down. I highly recommend Aloysius @ Gain city imm
